I went out to do chores just now to find my hen dead. I got her a couple months ago from a breeder at a show; he said she was older but would still lay eggs for me. She was a nice looking girl but she never actually laid for me until last week. It's been very hot outside--reaching in the 100's for the heat index--and that may have been the culprit. She was laying next to the water. It was pretty dirty but I change it every day. I don't know, could she have just been too old to stand the heat? Her eyes have always looked droopy so maybe she wasn't healthy. When I checked her out and her skin was very yellow (that could just be her skin color) and her comb was very purple. Other than that she was normal looking. And another thing is that I've been feeding her grower since she's mixed in with some 5 month old birds. I thought that was okay, but could it have been her diet? So help me out: was it probably the heat that got her or did she have some disease or worm? Should I worry about the rest of my flock? Thanks for your help.
